An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
